The IRND design of this filter has been optimized for use with digital sensors, and works to attenuate both visible and infrared light. Digital image sensors are more sensitive to a greater range of light spectra, and as such are prone to color shifts or casts when photographing darker subjects or scenes that require increased exposure times. This filter's unique design helps to suppress false colors for greater neutrality and faithful color reproduction.
This filter is made using ColorCore technology, a process that involves laminating the filter substrate between 2 pieces of optical glass, grinding flat to a tolerance of 1/10,000th of an inch, and mounting to precision metal rings.
- ND 3.0 filter darkens the image, allowing you to photograph with a longer shutter speed or wider aperture than normally required.
- Providing a 10 stop exposure reduction, this filter allows you to control depth of field and convey movement more easily.
- Attenuates infrared light, as well as visible wavelengths, to maintain color neutrality and suppress color casts due to increased exposure lengths.
